Which number line representation corresponds to \(\frac{x-2}{3}\ge 1\)?

Answer and explanation

Correct answer: Closed circle at 5 with shading to the right

In \(\frac{x-2}{3}\ge 1\), 3 is positive, so multiplying both sides by 3 does not reverse the inequality: \(x-2\ge 3\). Thus, \(x\ge 5\). Since 5 is included in the solution, the number line has a closed circle at 5 and shading to the right for values greater than 5. Option A would represent \(x>5\) because it uses an open circle. Exam tip: Use a closed circle for \(\ge\) or \(\le\).
